Product data sheet Rev. 1 — 3 September 2012 6 of 16 NXP Semiconductors 74LVC_LVCH245A_Q100 Octal bus transceiver; 3-state [1] All typical values are measured at VCC = 3.3 V (unless stated otherwise) and Tamb =25 C. [2] The bus hold circuit is switched off when VI >VCC allowing 5.5 V on the input terminal. [3] For I/O ports, the parameter IOZ includes the input leakage current. [4] Valid for data inputs of bus hold parts only (74LVCH245A-Q100). Note that control inputs do not have a bus hold circuit. [5] The specified sustaining current at the data input holds the input below the specified VI level. [6] The specified overdrive current at the data input forces the data input to the opposite input state.
